About this 1ct lab-grown radiant diamond

This 1ct lab-grown radiant sits in the classic one-carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included) and certified by IGI LG665403677 or 665403677. Listed at 17 retailers as of November 4, 2026, with prices from £169 to £1,300, a £1,132 spread on the same certified stone. Do Amore Diamonds lists it at £1,300. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
